FINERACT-2494: Add unit tests for ApiParameterHelper in fineract-core

[Ambika-Sony]

This Pull Request standardizes the operationId naming conventions within the Savings module API resources (SavingsAccountsApiResource.java).

By providing explicit and unique operationId values in the @operation Swagger annotations, we ensure that client-side SDKs (like the Fineract Java and TypeScript clients) generate clean, predictable, and user-friendly method names.

Key Technical Achievements
Architectural Migration: Successfully transitioned the standardization logic from the legacy fineract-provider structure into the new 1.15.0-SNAPSHOT modular architecture.

Upstream Synchronization: Performed a manual rebase against upstream/develop to resolve complex conflicts in GitHub workflows and the newly created fineract-savings sub-module.

Structural Integrity: Resolved JPA configuration path conflicts (persistence.xml) across multiple modules (fineract-loan, fineract-cob, fineract-investor) caused by the recent project refactor.

Clean History: Utilized a git reset --soft workflow to ensure a single, clean, and high-quality commit on top of the latest project state.

Verification Results
Local Build: Verified with ./gradlew :fineract-savings:compileJava — BUILD SUCCESSFUL.

Static Analysis: Verified that the new module paths are correctly mapped and that no new checkstyle violations were introduced in the Savings API resource.

Parity: Confirmed that all operationId values align with the patterns used in other standardized modules.

Hi @Aman-Mittal,

My apologies for the earlier confusion. A recent rebase onto the 1.15.0 modular structure accidentally included unrelated files from other modules.

I have now rectified the PR to align strictly with the FINERACT-2494 ticket scope. It now contains only:

ApiParameterHelper.java: Optimized regex logic.

ApiParameterHelperTest.java: Added a comprehensive JUnit 5 test suite covering command IDs, fields, locale, and pagination.

All unrelated changes have been removed, and the build is successful. Ready for re-review!
